一个泛型方法，你可以迭代它的结果:

public static Object[][] chunk(Object[] src, int chunkSize) {

    int overflow = src.length%chunkSize;
    int numChunks = (src.length/chunkSize) + (overflow>0?1:0);
    Object[][] dest = new Object[numChunks][];      
    for (int i=0; i<numChunks; i++) {
        dest[i] = new Object[ (i<numChunks-1 || overflow==0) ? chunkSize : overflow ];
        System.arraycopy(src, i*chunkSize, dest[i], 0, dest[i].length); 
    }
    return dest;
}

一个泛型方法，你可以迭代它的结果:

public static Object[][] chunk(Object[] src, int chunkSize) {

    int overflow = src.length%chunkSize;
    int numChunks = (src.length/chunkSize) + (overflow>0?1:0);
    Object[][] dest = new Object[numChunks][];      
    for (int i=0; i<numChunks; i++) {
        dest[i] = new Object[ (i<numChunks-1 || overflow==0) ? chunkSize : overflow ];
        System.arraycopy(src, i*chunkSize, dest[i], 0, dest[i].length); 
    }
    return dest;
}

我做以下，处理任何溢出:

var totalPages = totalResults.IsDivisble(recordsperpage) ? totalResults/(recordsperpage) : totalResults/(recordsperpage) + 1;

并使用这个扩展，如果有0结果:

public static bool IsDivisble(this int x, int n)
{
           return (x%n) == 0;
}

此外，对于当前的页码(没有被问到，但可能有用):

var currentPage = (int) Math.Ceiling(recordsperpage/(double) recordsperpage) + 1;

你可以使用

(int)Math.Ceiling(((decimal)model.RecordCount )/ ((decimal)4));

您需要执行浮点除法，然后使用ceiling函数将值四舍五入到下一个整数。

我有一个类似的需求，我需要将分钟转换为小时和分钟。我用的是:

int hrs = 0; int mins = 0;

float tm = totalmins;

if ( tm > 60 ) ( hrs = (int) (tm / 60);

mins = (int) (tm - (hrs * 60));

System.out.println("Total time in Hours & Minutes = " + hrs + ":" + mins);
